Cảm biến quang Takex (HMD) -Fiber radiation photo sensor- FD-A320 – Takex Việt Nam

• Double screen displaying threshold and receiving light intensity
  Displaying light intensity in numbers on double screen. One screen shows the light intensity when detecting heated material digitally from 0.0 to 12.0 in real time, and the other shows the threshold of output operation. The dynamic range of the amplifier is wide, and the wide temperature range of heated materials is displayed in analog.
• Current output of 4-20mA
  To survey assembly lines, this product outputs light intensity when detecting heated material, as an analog current.
• One sensor measures low and high temperatures
  Provided with two temperature ranges: one for low temperature and the other for high. The range can be changed using a switch.
• Simulation function
  Equipped with a simulation circuit for detecting heated materials. You can simulate the detection of heated materials with an external input.

Lowest Detectable Temperature

Select between two (high and low) temperature ranges with the mode setting

Guidelines are given below for the temperature of a detection object larger than the detecting field of view with optical head (OHA) and fiber optic cable (FG2) used for detection.
(The detectable temperature varies, depending on emissivity of the object.)

Guidelines for the minimum temperature of detection objects

The minimum temperature depends on the length of the fiber optic cable used or the detecting field of view of the optical head.
Temperatures shown in this table are for heated material larger than the field of view. If the material is smaller than the field of view, the lowest detectable temperature is increased. The guidelines are for the minimum temperatures of detection objects with margins of about four times as much as the inherent performance. For detailed data, see “Minimum Detectable Object and Lowest Detectable Temperature.”
